摘要

Production of alkyl tertiary butyl ether and a hydrocarbon stream containing 1-butene and a small amount of isobutene comprises using a catalyst volume in the side reactor (10) corresponding to 10-160% of the catalyst volume in the reactive distillation column (5). An independent claim is also included for a composition containing at least 25 wt.% 1-butene, 05.-7 wt.% alcohol and 10-2000 wppm isobutene.
